If visualization is more effective when accompanied by narration, why not superimpose visualization on narration? This might result in better transfer of learning. We will present a general framework for such superimposed visualization, called overlay visualization. The objectives for the design of our framework are 1) to separate the application from the visualization; and 2) to separate the specification from the rendering. We will describe a few applications of overlay visualization for programming and provide examples from our implementation of overlay visualization for software tutors called problets. The advantages of overlay visualization include: less cognitive load on the learner, and automatic support for both path and state visualization.
